What is EVP?

Electronic Voice Phenomenon (EVP) are intelligible voices found in recording media that have no known physical explanation. Many of the voices are thought to originate from deceased people. This is the primary reason that people first began experimenting with EVP.

Characteristics of the Voices

The recorded voices may be very quiet and may be difficult to hear and understand. Most EVP experimenters say that they have developed an “ear” for the sounds after learning to distinguish them from background noise. In transform EVP, the voices can often be recognized as male or female, young or old. Messages are seldom longer than two to four words. The words may be spoken very quickly, and there is often a distinctive cadence to the voices. Analysis shows that they are simulations of voice made from whatever sound is supplied, and are often missing voice box frequencies and have oddly arranged formants.

Types of Recording

In controlled conditions recording, it is possible to control ambient noise and supply special forms of background noise. Biofield energy is thought to accumulate in a “special” recording area, which is thought to help make contact. In field recording, it is difficult to control environmental conditions or supply background sound, but in known “haunted” locations, the energy helpful for contact may already be present.

EVP formed in an audio recorder by transforming available background sound is referred to as “transform EVP.” In this, it is sometimes possible to recognize the voice of the speaker. EVP formed by sweeping a radio dial, or with a computer program such as EVPmaker, are referred to as “opportunistic EVP” because sounds for voice formation must be made available on an “as needed” basis. Radio-sweep also known as "ghost boxes" or “spirit boxes,"), and in some applications, EVPmaker, depend on the use of “live” voice. ATransC will not use live voice examples for research because of the problem of undetected false positives. EVPmaker using synthesized voice is preferred for opportunistic EVP.

Environmentally stimulated speech synthesis is a relatively new and promising technique, but it should be noted that all speech synthesis approaches currently being tried do not support speaker recognition.


Recording Procedure

Recording Equipment

Digital voice recorders are recommended for transform EVP. Less expensive models produce more internal noise which is useful for voice formation. High quality units will probably require added background noise. A computer can also be used, but will probably require added noise.

Scheduling

Entities will speak at any time of day or night. In the beginning, however, it is advisable to record at a regular time and place. By doing this, the entities learn when there will be an opportunity for contact and expectation of the upcoming session helps focus attention on the process. Try to find a place that will be quiet and free of interruptions. Background sounds are okay, but it is important to be aware of these so that they can be distinguished from the EVP.

Background Sound Source

Research has shown that for transform EVP, the entities use sounds in the environment to help form the words. Most recording situations have some background sounds, but it may be necessary to add noise with something like a fan or running water. Some people use foreign language radio, crowd babble or audio tapes; however, as more has been learned about EVP, the recommended practice has been to avoid the use of radio static or live voice of any form. Please see Using a Computer to Record for EVP for more discussion about sound sources.

Preparation

Begin with meditation and a short prayer to ask for only those intending the highest good and an invitation to friends on the other side to participate. It is best to record when personal energy is the highest.

Recording

Vocalize your comments during an EVP session. The entities will often come through as soon as the recorder is turned on. These beginning messages may be the loudest, so it is a good idea to turn on the recorder and wait a few seconds before speaking. Questions should be recorded, and a period of time between each comment should be left for the entities to respond--about ten seconds. At the end, ask if the entity has something to say.

It may help to make an “appointment” with the intended entity the day before, during prayer or meditation. Some also provide feedback before the session so that the entities will know what worked in the last experiment. It is not necessary to record in the dark. People often try different devices and energy sources to help the entities communicate. Leaving written questions in the EVP experiment area the day before has worked for some.

Keep recording short. Recordings should be closely examined, at least until it is understood where to find the voices. A best practice for field recording is to use two recorders. As a rule, EVP will only occur on one recorder or sound track, making it possible to avoid mistaking local sounds for EVP (false positives).

Playback

In transform EVP, the voice is usually not heard until playback. Experimenters report that the voices tend to become stronger and clearer as the entities gain in experience, but at first the voices may speak in whispers. Voices may not be recorded in every session and it may take several sessions to discover the first voice. Hearing the voices is a learned ability. It might take thirty minutes to examine a three or four minute recording.

Classes of Voices

The following system of classification is based on a Best Practice being developed in the Collective at atransc.org/bp/Classification#Practice. You are invited to participate in developing the practice. Please use the Contact tool to let us know you are interested.

A distinction is made between phenomena which are always present and phenomena which are transient features. A face seen in the decomposition pattern of a leaf is more or less always there, as opposed to a face found in moving water or video-loop noise. As a general rule, “always there” phenomena appears to be formed by opportunistically adapting naturally occurring processes to express the message, assuming one is intended. If perceived as phenomena, “always there” features would be considered Type 2.

Features found in ever-changing noise are thought to be formed by transforming that noise into the voice or face. While the resulting features are fleeting unless caught in media (photograph or audio recording), they tend to be better formed and more easily identified as anomalous. So for both audible and visible phenomena:

Type 1: Transformed physical media; not always present

Type 2: Always present; often as a persistent artifact

Both Type 1 and Type 2 examples are divided by three classes:

Class A: Evident without explanation

Class B: May require directions

Class C: May be vaguely experienced; mostly obscured by noise

Keeping a Log

Maintaining a record of recording results is very helpful. Include the date, time, seconds into the recording, the message itself and the question asked. Be sure to label and save the audio file so that they can be found at a later time. Experimenters report that they feel weather may affect results, but this has not been well studied. The Geoweather page has Geomagnetic and solar reports. There is also a link for moon phase information, as well.

Digital Voice Recorders

Digital voice recorders are recommended for EVP experiments. Today, all sound tracks—digital or analog—should be listened to in a computer and with a headset. Unlike tape recorders, the built-in microphone is usually satisfactory for EVP. There is a selection guide for audio recorders here. The section includes a setup guide for Audacity, which is an effective audio management program that can be downloaded at no cost.

Computer Recording

A computer instead of a digital recorder can be used for recording EVP. It should have an audio input jack, speakers, headphone jack and sound player application such as Audacity. Most experimenters use the computer to analyze and store examples. If the recorder does not have a USB interface, it is possible to play the recording into the computer while recording with a recorder program. The Earphone jack of the recorder can be connected to the Microphone or Line 1 jack via a cable. The sound source should be set to the correct jack via the pull-down menu in Audacity. Recording with a sample rate of 11025, mono and 16 bit resolution is sufficient for EVP. Files should be edited as *.wav format, but shared as *.mp3.

Analyzing the Recording for EVP

Always use headphones when listening to the recording in a computer. The earmuff style that completely covers the ear is best, but also good are the soft rubber ear buds that are inserted in the channel of the ear.

Be sure to set up a method of saving your recordings in your computer that will allow you to easily locate examples. A good practice is to save the raw recording session in a dated folder and then also save clips containing the EVP in the same folder. Field recordings are saved under the name of the location and the date. It is helpful to keep a separate folder for your Class A examples for easy retrieval for demonstration to friends. ATransC follows the labeling practice of: (c)lisa_butler2008-what_evp_says.mp3. The (c) symbol indicates the intention to protect rights to the example. If you are making the example available under the Creative Commons license, then use (cc) instead of (c). Using first and last name helps sort many examples in the folder for easy retrieval. The underline and dash symbol with no use of capitals helps assure that computer systems and the Internet accept the name. A 200 kb audio file can be reduced to around 15 Kb when converted from a *.wav file to an *.mps file. This makes it easy for sharing files via the Internet.

Classes of Voices

A Class A voice can be heard and understood over a speaker by most people.

 

A Class B voice can be heard over a speaker, but not everyone will agree as to what is said.

 

A Class C voice can only be heard with headphones and is difficult to understand. Class B or C voices may have one or two clearly understood words.

Loud does not equal Class A.
